One thing about this machine that is truly surprising, is just how small the teeth are.

There's a well established theory as to how the tooth divisions were marked out, but employing that process to mark out multiple wheels has forced me to question whether it can reasonably be applied to the Antikythera Mechanism.

So in this video I propose an alternative process of wheel division, using only the non precision tools of the period.​

In this episode the basic structure of the mechanism comes together, and I put forward a theory on a simple method for achieving the extremely close clearances observed in the original device.​Its an extra length episode for you folks, so please enjoy!​
